Update MBUX Multimedia System Software – 2022 Mercedes-Benz EQS-Class & S-Class

SEOCONTENT-START

This notice applies to your vehicle, VIN: Update MBUX Multimedia System Software MBUSA ID: 2022080002, NHTSA Recall ID: 22V493 August, 2022 • A remedy is now available for your vehicle. • Schedule an appointment with your authorized Mercedes-Benz dealership as soon as possible. • This repair will be provided FREE of charge. Dear Mercedes-Benz Owner: This notice is being sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has decided that certain Model Year (“MY”) 2021-2022 EQS-Class and S-Class vehicles fail to conform to Federal Motor Vehicle Safety Standard No.111, “Rear Visibility.” Our records indicate that your vehicle is included in the affected population. What is the issue? When the vehicle is unlocked, due to an error in the MBUX multimedia system software, the central display may not activate. When the driver engages reverse gear the rearview camera image might not be displayed in the central display. Instead, the central display would remain black. As the vehicle begins to back up, the blackened rearview camera display would impair rear visibility which could increase the risk of a crash. What will your Mercedes-Benz Dealership do? As a precautionary measure, MBAG, via its Mercedes-Benz service partners, will update the MBUX multimedia system software on the affected vehicles. This vehicle repair will be provided at no cost to you. While the minimum repair time can be less than 30 min, your dealership can provide you with a better estimate of the overall time for this service visit. As a matter of normal service process, an authorized Mercedes-Benz dealer will also check for other repair measures that might be applicable to your vehicle which may increase the required working time. You will not be charged for other service or repairs unless so requested. Steps to take. • Find your nearest authorized Mercedes-Benz dealership at mbusa.com/recalls to schedule your recall repair. • Please mention you are scheduling an appointment for Mercedes-Benz Recall Campaign 2022080002. • You may be asked for your VIN, which for your convenience is located at the top of this letter. We apologize for any inconvenience this may have caused and look forward to taking care of this important safety recall campaign.

FMVSS 1 : 111 – Rear visibility FMVSS 2 : NR Description of the Safety Risk : As a result, the central display might not be activated as intended when the vehicle is unlocked. In this case, the rearview camera image might not be displayed in the central display when the driver engages reverse gear. Instead, the central display would remain black. A deactivation or freezing of the rearview camera image during reverse driving can be excluded. A rearview camera picture that might not be available within 2.0 seconds (as required by FMVSS 111 S5.5.3) when beginning to back up might impair rear visibility which might increase the risk of a crash. Description of the Cause : Due to deviations in the development processes of two different suppliers, the MBUX multimedia system software on certain vehicles might not meet current production specifications. Identification of Any Warning that can Occur : Before the issue occurs, the driver will not receive a warning due to the nature of the failure mechanism. When the issue occurs, the driver might notice that the central display is not activated and, thus, the reversing camera function is not available. Involved Components : Component Name 1 : See Supplemental Document Component Description : See Supplemental Document Component Part Number : See Supplemental Document Supplier Identification : Component Manufacturer Name : Gigabit Multimedia Serial Link (GMSL) Au Address : 160 Rio Robles San Jose California 95134 Country : United States Part 573 Safety Recall Report 22V-493 Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 Chronology : In April 2021, MBAG received isolated reports (outside the US) of the MBUX head unit central display failing to activate and remaining black upon unlocking of S-class vehicles. MBAG commenced an investigation in coordination with the supplier. While these analyses were ongoing, the supplier started to develop a more robust software version as an adhoc measure. This software version was substituted in series production beginning in August 2021. In parallel, the root cause analyses were still ongoing and potentially affected head units from the field were sent to the development department for further investigation. In November 2021, MBAG received two field reports of a central display screen failure to activate (outside the US) in EQS model cars, and began to investigate those reports. Later, MBAG determined the reported display failures were similar to the ones in the S-class vehicles and initiated an investigation to determine if those occurrences may have a common cause. In spring of 2022, the investigation determined that although the driver experiences the similar start up behavior of the central display —a black screen– the two cases had different causes within the software of the head unit. For the S-class vehicles, MBAG identified a software deviation that could cause the central display not to activate upon unlocking the vehicle. For EQS vehicles, MBAG identified a different software deviation that could also cause the central display to stay black upon unlocking those vehicles. In June 2022, MBAG determined and identified the potentially affected vehicle populations for both the S-class and the EQS vehicles in the field. On July 1, 2022, MBAG determined that a potential non-compliance cannot be ruled out and decided to conduct a recall of potentially affected S-class and EQS vehicles. Please see supplemental chronology of defect posted 7.11.2022. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will update the MBUX multimedia system software on the affected vehicles. Pursuant to 49 C.F.R. § 577.11, MBUSA does plan to provide notice about pre-notice reimbursement to owners since most of the involved vehicles would have been previously subject to the condition described and customers who have already paid to have this recall condition corrected may be eligible to receive reimbursement. How Remedy Component Differs from Recalled Component : Software of the MBUX multimedia system on the affected vehicles according to current production specifications. Remedy Part EQS (BR 297): MBUX multimedia system software: A2979043200 Remedy Part EQS S-Class (BR 223): MBUX multimedia system software: A2979042800 Part 573 Safety Recall Report 22V-493 Page 5 The information contained in this report was submitted pursuant to 49 CFR §573 Identify How/When Recall Condition was Corrected in Production : Changes in the development processes of our suppliers ensure that this issue can no longer occur from March 24, 2022 onwards.
